Things to Consider for Chicago Marathon Event

* Pay attention to the most up-to-date weather forecast and dress for the appropriate weather conditions.
* Be prepared for warmer temperatures throughout the day and do not overdress. Keep in mind that you can always shed a layer as your body and the day warms up.
* Avoid heavy cotton fabrics that absorb and retain moisture; opt for lightweight technical fabrics that shed moisture and wick sweat away from the body.
* Wear sunglasses and waterproof sunscreen. With the amount of time you will be on the course, you want to protect your skin and eyes.
* Study the course and be aware of the locations of Aid Stations. Each Aid Station has water, Gatorade, toilets, medical facilities and access to runner drop-out vehicles
* Utilize both water and sports drinks (Gatorade) to stay hydrated and maintain sodium levels.
* Start out at a conservative pace, particularly in warmer weather which requires more of your body's resources to maintain normal function. Conserve your energy for the latter stages of the race.
* Listen to your body. If at any time during the race your body gives you signals to slow down or to stop, abide by them. Be aware of your heart rate, body temperature and hydration levels.
* Do not immediately stop moving when you cross the finish line. Rather, walk or slowly jog as you move through the finish area. This will allow your muscles to relax and your body to acclimate. It is not uncommon for runners to collapse beyond the finish line due to the sudden change in activity.
* For participants who require such assistance after the race, the Main Medical facility is located just beyond the finish line, as is an Ice Tent and Podiatry Tent.
* Hydration: Drink enough fluids to maintain your baseline body weight, but be aware of over-hydration. If you begin to gain weight above your baseline body weight, you are drinking too much water and depleting your sodium level. (A condition known as "Hyponatremia" can occur when there is a lower than normal concentration of sodium in the blood. Sodium is a critical electrolyte that aids nerve and muscle function, and helps to maintain blood pressure.)
